Table 8.1 Error code list (Continued)
Error code Description Corrective action
F820 Link parameter error
Replace the network module of the normal station with the one compatible with
the MELSECNET/H Extended mode.
Change the network type of the normal station to that of the control station.
Create new network parameters and perform Write to PLC.
If the error reoccurs, the hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
F821 Station-specific parameter error
Review station-specific parameters.
Set common parameters
station-specific parameters for the sending range
of the host station.
If no station-specific parameters are set, the hardware of the CPU or network
module is faulty.
Please consult your local Mitsubishi representative.
F822 System error
The hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
F823 Parameter consistency error
Set common parameters
station-specific parameters for the sending range
of the host station.
If no station-specific parameters are set, the hardware of the CPU or network
module is faulty.
Please consult your local Mitsubishi representative.
F825 CPU parameter check error
Perform Write to PLC on the network parameters for the control station again.
If the error reoccurs, the hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
F826 Parameter mismatch error
Set parameters suitable for the sub control station, or activate it as a control
station.
Review and reset the parameters for the master and sub master stations.
If the error reoccurs, the hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
F828 No control station shift setting Set "with data link by the sub control station when the control station is down."
F829 Pairing setting error
On the network parameter at control station, set the paring setting on the
Redundant CPU or unset the paring setting on all the CPUs other than the
Redundant CPU.
F82A
Network type mismatch (normal station
detected)
Match the network type set for the normal station with the one set for the control
station.
F82B
Network type mismatch (control station
detected)
F830 System error
The hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
F831 System error
F832 Data link startup condition error
If the data link is stopped under all station specification, start it by all station
specification.
If the data link is stopped under specific station specification, start it from the
station, or forcibly start it.
F833 Keyword error Start the data link from the station where it was discontinued, or forcibly start it.
F834 System error
The cable is faulty, or the hardware of the network module is faulty.
If a communication error has occurred, review the cable.
If not, the hardware of the network module is faulty.
Please consult your local Mitsubishi representative.
F835 System error
F836 System error
F837 Exceeded number of retries
Check the status of the control station and of the remote master station (to see
if resetting or an error occurs in the middle of the operation).
F838 Relevant timer timeout
Check the status of the control station and of the remote master station (to see
if resetting or an error occurs in the middle of the operation).
F839
No link parameter
(communication impossible)
Register link parameters
F83A SW0000 out of range error Correct the contents of SW0000.
